Detailed implementation mode

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the drawings.

[0026] The present utility model provides a copper busbar that can be connected in multiple positions as shown in Figures 1-5 , including a main copper busbar 1;

[0027] A connection mechanism 6 is installed at both ends of the main copper busbar 1 for connection. An arc portion 2 is provided in the middle of the main copper busbar 1, and a protective cover 3 is sleeved outside the arc portion 2. First connection holes 4 are opened on both inner sides of the protective cover 3;

[0028] A secondary busbar 7 is connected to one side of the connection mechanism 6 for increasing multi-position connection, which can provide multiple current paths, enhance the flexibility and scalability of the system. In the case of large current demand, the multi-position connected copper busbar can disperse the current load and reduce the current density of a single path, thereby improving the stability and safety of the system. The multi-position connection is improved by opening a plurality of first connection holes 4 on the surface of the main copper busbar 1 itself. At the same time, the main copper busbar 1 can be connected to the secondary copper busbar 703, and a plurality of second connection holes 704 are also opened on the secondary copper busbar 703, further increasing a plurality of connection positions, thereby improving the flexibility and scalability of the copper busbar.

[0029] Such as Figure 1 , Figure 2 andFigure 3 As shown in the figure, first heat dissipation holes 5 are provided on both inner sides of the main copper busbar 1. The first heat dissipation holes 5 are located on one side of the first connection holes 4. By providing a plurality of first heat dissipation holes 5 on the surface of the main copper busbar 1, the contact surface area between the main copper busbar 1 and the surrounding environment is increased. The increase in the surface area means that more heat can be dissipated into the air faster, thereby improving the heat dissipation efficiency.

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in the figure, the connecting mechanism 6 includes an upper copper busbar 601 and a lower copper busbar 602. The upper copper busbar 601 and the lower copper busbar 602 are installed at both ends of the main copper busbar 1. First mounting holes 604 are provided on the inner surfaces of the upper copper busbar 601 and the lower copper busbar 602. A bolt 605 passes through the inside of the first mounting hole 604. One end of the bolt 605 is movably connected to a nut 606. By inserting a connecting block 701 on one side of the auxiliary copper busbar 703 between the upper copper busbar 601 and the lower copper busbar 602 on one side of the connecting block 701, and then inserting the bolt 605 into the second mounting hole 702 inside the first mounting hole 604 and the connecting block 701, and finally sleeving the nut 606 on one end of the bolt 605 and tightening it for fixation.

[0031] As Figure 3 and Figure 4 As shown in the figure, tooth grooves 603 are provided inside both the upper copper busbar 601 and the lower copper busbar 602. The tooth grooves 603 are evenly distributed inside the upper copper busbar 601 and the lower copper busbar 602. The tooth grooves 603 provided on the inner surfaces of the upper copper busbar 601 and the lower copper busbar 602 increase the friction between the connecting block 701 and the upper copper busbar 601 and the lower copper busbar 602, thereby improving the firmness of the connection.

[0032] As Figure 1 、 Figure 4 and Figure 5 As shown in the figure, the auxiliary busbar 7 includes a connecting block 701. The connecting block 701 is installed inside the upper copper busbar 601 and the lower copper busbar 602. A second mounting hole 702 is provided on the inner surface of the connecting block 701. One side of the connecting block 701 is fixedly connected to an auxiliary copper busbar 703. The material of the connecting block 701 is copper. The auxiliary copper busbar 703 is inserted into the gap between the upper copper busbar 601 and the lower copper busbar 602 through the connecting block 701. The bolt 605 passes through the first mounting hole 604 and the second mounting hole 702 provided inside the connecting block 701, thereby completing the connection between the auxiliary copper busbar 703 and the main copper busbar 1.

[0033] As Figure 5As shown, second connection holes 704 are provided on the inner surfaces of the auxiliary copper bars 703, and second heat dissipation holes 705 are provided on the inner surfaces of the auxiliary copper bars 703. Through the multiple second connection holes 704, the flexibility of multi-bit connection can be improved, and at the same time, the contact surface area between the auxiliary copper bars 703 and the surrounding environment is increased, thereby improving the heat dissipation efficiency.

[0034] The working principle of this utility model: First, insert the connection block 701 on one side of the auxiliary copper bar 703 between the upper copper bar 601 and the lower copper bar 602 on one side of the connection block 701. Then, insert the bolt 605 into the first mounting hole 604 and the second mounting hole 702 inside the connection block 701. Finally, put the nut 606 on one end of the bolt 605 and tighten it. Through the teeth 603 provided on the inner surfaces of the upper copper bar 601 and the lower copper bar 602, the friction between the connection block 701 and the upper copper bar 601 and the lower copper bar 602 is increased, thereby improving the firmness of the connection. Then, the wires to be connected can be connected to the first connection holes 4 on the main copper bar 1 and the second connection holes 704 on the auxiliary copper bar 703. Through the multiple first connection holes 4 and second connection holes 704, not only can multiple current paths be provided, enhancing the flexibility and scalability of the system, but also in the case of large current demand, multi-bit connection can disperse the current load and reduce the current density of a single path, thereby improving the stability and safety of the system. Just like this, the use process of the multi-bit connectable copper bar is completed.
